title: N,N-Diethyl-4-[1-phenyl-3-(pyridin-2-yl)-4,5-di-hydro-1H-pyrazol-5-yl]aniline.
abstract: In the title mol-ecule, C24H26N4, the pyrazoline ring assumes an envelope conformation with the aniline-bearing C atom at the flap position. The benzene ring and the pyridine ring form with the pyrazoline ring dihedral angles of 4.53 (1) and 6.26 (1)°, respectively. In turn, the aniline group is nearly perpendicular to the pyrazoline ring [dihedral angle = 79.96 (1)°]. The ethyl groups of the di-ethyl-amine substituent are disordered over two sets of sites, with an occupancy ratio of 0.624 (8):0.376 (8).
